I'd really be wary of trying techniques like this. If you're concerned about accessibility, that's what the alt and title attributes are for. display: none runs a good chance of getting you blacklisted on Google, and it's a possibility that they have some CSS position identification either implemented or planned for the next few years. It's borderline stuff.

beaner15: That shouldn't be happening; sorry for the apparent bug there. If you could, please file a bug report with some more details on your browser and operating system and I'll look into it further. Thanks!
